Exton originally in [1]}, [2]} and later Koelink and Swarttouw in [3]}, proved that the function (REF ) satisfies an orthogonality of the form
\(\int _{0}^{1}xJ_{\nu }\big (qj_{n\nu }x;q^{2}\big )J_{\nu }\big (qj_{m\nu }x;q^{2}\big ){\rm d}_{q}x=\eta _{n,\nu }\delta _{n,m},\\\eta _{n,\nu }\equiv \eta _{n,\nu }(q)= \int _{0}^{1}tJ_{\nu }^2\big (qj_{k\nu }t;q^{2}\big ){\rm d}_{q}t ,\nonumber \)
